STEERING OF THE BOILER
The boiler is steered by means of the electronic regulator (digital boiler regulation),
which is built into the boiler on its upper side and has an steering and protecting
function. The functions of the boiler regulations are described in the Point 7.0 and in
Tecnical manual "Digital boiler regulation Bio-Tec".

Boiler regulation
7.0. BOILER REGULATION
-
Main switch (power supply switch) has the function to turn on / off the
regulator.
- LED display shows the measured temperatures, their ordinary number,
number or parameter value as well as the regulator functioning mode signal.
- Indication "START" (LED diode) shows the regulator functioning mode
(ignition/operation).
- "START"-button.
- "P"-button.
- "+"-button.
- "-/STOP"-button.
- "GLOW"-button.
- Indication "GLOW" (LED diode). Indicates the active functioning of the burning
process with glow keeping. This burning process mode can be turned on/off by
pushing the button 8.
- Indication "FUEL" (LED diode) indicates that after the period of the boiler
warming up has run out, the flue gases temperature is under the setup level for
burning with or without glow keeping. It is not recommended to open the boiler's
door while the indication ''FUEL'' is NOT on.
- Indication "FAN" (LED diode) indicates that the fan is turned on/off.
- Indication "ERROR" (LED diode) indicates that the error appeared during the
boiler functioning.
- Indication "PUMP 1" (LED diode) indicates that the relay for the P1 supply is
turned on/off.
- Indication "PUMP 2" (LED diode) indicates that the relay for the P2 supply is
turned on/off.
- Indication "PUMP 3" (LED diode) indicates that the sanitary water pump is turned
on/off.
